SCR Phase-shift Triggers

I. Overview

    The JKH-C1 phase-shift trigger/voltage regulator adopts a high-performance switching power supply and offers multiple control input specifications with optoelectronic isolation between input and output. It can be used together with various automation instruments, and can also be used directly as a 0-220V, 0-380V/500W voltage regulator. In automatic control it does not interfere with the instrument. It is widely used in control systems where the load requires continuous smooth regulation, where high control accuracy is required, or where high inrush current is not permitted, such as speed control, voltage regulation and charging of AC/DC motors. Wiring is simple, there is no synchronizing transformer, and the phase sequence need not be considered. Reliable overcurrent protection ensures that damage to the SCRs in the main circuit will not cause damage to the controller; even if the trigger wires are connected incorrectly, the controller will not be damaged within a short period.
    The JKH-C1 phase-shift trigger/voltage regulator is panel-mounted, allows free switching between manual and automatic modes, and indicates output power dynamically with a light bar, making operation convenient.
